Technical Field
[0001] The present invention relates to the field of pelvic floor muscle repair, and specifically refers to a pad-type pelvic floor muscle repair instrument. Background Art
[0002] The pelvic floor muscles, namely the pelvic floor muscles, as a group of muscles that enclose the pelvic floor, are like a "hanging net", tightly suspending organs such as the urethra, bladder, vagina, uterus, and rectum, maintaining their normal positions, and having multiple physiological functions such as controlling urination, defecation, and maintaining vaginal tightness. Pelvic floor muscle dysfunction refers to a group of diseases caused by damage or abnormal function of the pelvic floor support structure, often due to reasons such as childbirth and aging. Its symptoms include functional disorders such as urinary incontinence, vaginal prolapse, and uterine prolapse. The principle of existing pelvic floor muscle repair electronic instruments is to use electric current or electromagnetic pulses to stimulate the pelvic floor muscles to cause them to contract, so as to restore their effective supporting effect on organs such as the urethra, bladder, vagina, uterus, and rectum. However, the existing pelvic floor muscle stimulators mainly have two working modes: one is to insert a rod-shaped electrode into the vagina or anus and apply a stimulating current pulse to cause the pelvic floor muscles to contract, and the other is to apply a high-intensity electromagnetic pulse to cause the pelvic floor muscles to contract.
[0003] In the prior art, there has already appeared a pelvic floor muscle repair instrument that performs electrical stimulation on the body surface of the pelvic floor muscles.

[0028] The following further describes the present invention in conjunction with the drawings and specific embodiments.
[0029] Refer to Figures 1 - 4, a pad - type pelvic floor muscle repair device. The pad - type pelvic floor muscle repair device includes a pad main body 1 and an electrode assembly 2. The pad main body 1 is made of a flexible deformable material, which can be made of polymethylvinylsiloxane, polysiloxane, polyvinyl chloride, polyurethane, polyethylene or polypropylene. The pad main body 1 can be made of flexible silicone, plastic or a waterproof and insulating material at positions where flexible deformation is required. A micro - current generating device 3 is also provided inside the pad main body 1. The micro - current generating device 3 is connected to the electrode assembly 2. When the electrode assembly 2 comes into contact with the user's pelvic floor muscle part, a conductive circuit is formed among the electrode assembly 2, the micro - current generating device 3 and the pelvic floor muscle part. The micro - current generating device 3 can generate bio - electrical stimulation of a specific frequency to perform current stimulation repair on the pelvic floor muscles. In this embodiment, the micro - current generating device 3 includes a rechargeable power supply component 31. Therefore, the pad - type pelvic floor muscle repair device does not need to be connected to a wire and can be carried around during use, which is convenient for use.
[0030] At least one working end face 11 of the pad main body 1 corresponds to the user's pelvic floor muscle part. The electrode assembly 2 is arranged on the working end face 11. The electrode assembly 2 is used to apply current stimulation to the user's pelvic floor muscles. Among them, the electrode assembly 2 includes a water - permeable conductive layer 21. A plurality of grooves 13 are arranged in an array on the working end face 11 of the pad main body 1. The conductive layer 21 covers the plurality of grooves 13. The plurality of grooves 13 are used to hold the water that penetrates from the conductive layer 21. When the user is using it, the user can sprinkle or spray water on the conductive layer 21. The water penetrates through the conductive layer 21 and enters the plurality of grooves 13. The conductive layer 21 covers the openings of the plurality of grooves 13 or is spaced apart from the openings by a small distance. Therefore, a water storage space is formed between the conductive layer 21 and the grooves 13. The water contained in the grooves 13 can moisten the conductive layer 21 during use, so that a good conductive performance is established between the conductive layer 21 and the user's pelvic floor muscle part.
[0031] The size of the groove 13 is configured to adsorb at least the water permeating from the conductive layer 21 through the surface tension of the liquid. When the size of the groove 13 is small enough, the water can be stored by the tension of the water. Taking the pad body 1 made of silica gel or flexible plastic as an example, in order to achieve the moisturizing adhesion effect, the radius of the inscribed circle of the groove 13 is less than or equal to 3.2 mm. The calculation process is as follows: The critical condition for a water droplet to drip is that the self-gravity of the water droplet is greater than or equal to the surface tension of the water droplet. The critical condition for a water droplet to drip is that the self-gravity of the water droplet is greater than or equal to the surface tension of the water droplet. The surface tension of water f = a×l, where a is the liquid surface tension coefficient and l is the length of the liquid surface boundary line. For water, in an environment of 20 degrees Celsius and 1 atmosphere, the surface tension coefficient a of water on the pad body is 0.072 N / m, and the gravity is determined by the mass of the water, which is calculated through the volume and density of the water droplet. F = mg, where F is the gravity of the water droplet, m is the mass of the water droplet, and g is the acceleration due to gravity. F = Vρg, where V is the volume of the water droplet. Therefore, So ρ is the density of water and r1 is the radius of the water droplet.
[0032] When the water droplet adheres to the groove 13 on the pad body 1, under extreme conditions, the acting end face 11 of the pad body 1 is placed vertically. At this time, the water droplet is not affected by force in the horizontal direction, and the water droplet is only affected by the surface tension and gravity. Therefore, at this time, the surface tension and gravity of the water droplet are equal. In the above equation, l is the circumference of the inscribed circle of the groove when the water droplet is located on the groove. Therefore, l = 2πr2, where r2 is the radius of the inscribed circle of the groove, that is, Here, let r1 = r2, that is, the maximum radius that the water droplet on the groove can reach (that is, the critical radius of the water). Through the formula, we can calculate that the critical radius r1 of the water is about 3.2 mm, and the radius r2 of the inscribed circle of the groove is less than or equal to 3.2 mm.
[0033] In this embodiment, the outer contour of the groove 13 is hexagonal, but it can also be a circle, ellipse, triangle, quadrilateral, pentagon and other polygons with an inscribed circle radius less than or equal to 3.2 mm.
[0034] The skin hair and dryness on the surface of the pelvic floor muscles will increase the skin contact resistance value and decrease the current value of bioelectrical stimulation (EMS), affecting the curative effect and body sensation. Therefore, good water locking is required to keep the skin resistance nearly unchanged and achieve the expected treatment effect. The interval between two adjacent grooves 13 is between 0.5 mm and 0.6 mm, which can minimize the non-water storage area.
[0035] In this embodiment, the multiple grooves 13 are all adjacent to each other.
[0036] In some other embodiments, the multiple grooves 13 are divided into multiple groups of discretely arranged groove groups 13, and the spacing distance between two adjacent grooves 13 in each groove group 13 is between 0.5 mm and 0.6 mm. The number of grooves 13 in each groove group 13 is at least 4. The discretely distributed groove groups 13 can form discretely distributed conductive positions on the contact surface for dot-like treatment.
[0037] In this embodiment, the electrode assembly 2 includes at least a pair of electrodes 22, and the electrode 22 includes the conductive layer 21. The electrode assembly 2 includes two pairs of electrodes 22 spaced along the length direction of the pad body 1, and each pair of electrodes 22 includes two electrodes 22 spaced along the width direction of the pad body 1. The electrode 22 is detachably connected to the pad body 1, and the electrode 22 and the pad body 1 are connected through an electrical contact 23; alternatively, the electrode 22 is fixedly connected to the pad body 1. In this embodiment, the pad body 1 and the electrode 22 are detachably connected through a magnetic attraction structure or a snap structure.
[0038] The conductive layer 21 is made of fiber conductive cloth, which can be permeable to water and has good electrical conductivity, and the fiber gaps can have good water retention performance. In this embodiment, the electrode 22 is made of silver nylon fiber conductive cloth, which has strong flexibility, good electrical conductivity, and good permeability.
[0039] In this embodiment, one side of the pad body 1 opposite to the acting end face 11 defines a connection end face 12 for connecting with the user's clothing. The connection end face 12 can be connected to the user's clothing and skin by pasting.
[0040] During use, the user only needs to use a spray device or directly spray water on the surface of the electrode 22, so that the grooves 13 lock the moisture through the surface tension of the water. When the conductive layer 21 contacts the user's pelvic floor muscle skin, the electrode 22 can establish a good and stable conductive circuit with the pelvic floor muscle, and the microcurrent generating device 3 can apply current stimulation to the pelvic floor muscle. The connection end face 12 can be connected to the user's clothing by pasting to achieve the effect of carrying treatment with the user at any time, and the rechargeable power supply component 31 realizes a wireless effect.
[0041] The above is only a preferred specific embodiment of the present invention, but the design concept of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention who makes non-substantive modifications to the present invention using this concept shall fall within the scope of infringement of the present invention.
